umm, i really haven''t thought about it, but if they did it anything like Quake 2, it would probly work off a waypoint/path-based systemI have noticed in some of the levels, the AI does the same thing over and over, and thats how i come to this conclusion.

The bots are looking on the floor.. That means they don''t use any keypoint-system, the game saves information of the surrounding area in every floor tile.. so the bot-ai reads this information and decide where to go or what to do...And they''re walking the same way sometimes because the bot''remembers'' where weapons where located and what''s the shortest way to them...
